On the delicacy's pronunciation
I'd suggest "smajhenee seer" as the closest approximation in the Queen's tongue, with the final "R" borrowed from Spanish, rather than English. (try readspeaker.com for the real version)
My family's tradition definitely calls for a Camembert-style cheese, though almost any cheese with a stronger flavour will do. Feel free to experiment with diced/mashed spuds, but do not skimp on the tartar sauce, if you've already got a decent mayo. Just add some finely diced pickles and onion to bring the flavour out.
Given the meal's fat content, I wholeheartedly recommend a pint of your favourite Pilsner as a digestive.
